FWIW, TBs on dimmers (in my house, anyway) seem to last much longer than TBs on straight switches.

This is true. You are lowering the voltage to the bulb, and therefore the bulb's filament temperature. The Tungsten doesn't boil off as fast......

I have no doubt she’s right about what’s causing her headaches, but curious as to what they might have changed to cause problems now but not last year?

Did she move from a room/area with windows and sun exposure to one without? Many older schools have windows for all classrooms. Many newer ones do not. Maybe she is getting nothing but fluorescent now.

> TBs on dimmers (in my house, anyway) seem to last much longer than TBs on straight switches <

It’s a well-known effect among lighting professionals.

A dimmer allows the bulb’s tungsten filament to come gradually up to operating temperature, rather than the near-instaneous heating that occurs with a switch-operated light.

Therefore the dimmer puts much less strain on the tungsten than does a switch.

Anybody who has ever worked in lighting for TV or movie production will tell you that the large Klieg lights in studios usually have dimmers, and the operators are instructed to bring the lights gradually up to temperature in order to extend the bulbs’ lives.

Didn't last a year......

I've been using them in some areas of my house and having that same experience. Heck, I even have some bulbs that were in the house when I bought it 3 years ago that are still burning while these darn CFLs continue to burn out. I think I'm done with them.

Don’t drop one or you’ll have to leave your home.

be careful - if you break one, Im told there is mercury vapor inside - have heard stories about rooms being contaminated

It would take thousands and thousands of these bulbs to get enough mercury to equal that in a small thermometer. So that part doesn't bother me ... they just don't last long like they're supposed to.

How do we dispose of the ones that have stopped working? Since they are full of toxic material?

Take them to Home Depot or Lowe's. Also, see my previous message about the very low mercury content.

That’s where you’re wrong, it goes airborne and you breath it in, read the instructions on what do if one breaks, you have to remove your carpet, never vacume it, leave the home, for days, to be honest, in most cases you need to contact a hazmat team, if you don’t believe me I can post the official guidelines.

No you won't. Each bulb contains about 5 milligrams ... that's about the size of the period at the end of this sentence.

EPA instructions for a broken bulb are:

Before Clean-up: Air Out the Room

Clean-Up Steps for Hard Surfaces

Clean-up Steps for Carpeting or Rug

Clean-up Steps for Clothing, Bedding and Other Soft Materials

Disposal of Clean-up Materials

Future Cleaning of Carpeting or Rug: Air Out the Room During and After Vacuuming

My point exactly, I want to go through that and expose my children to mercury at dangerous levels why again?

No, your point was “you have to leave your house for days and call hazmat”

I remember many, many broken fluorescent bulbs through the years ... you know, those long ones .... while working in various places. Never have I heard about or experienced any health issues due to those broken tubes. I think there is more hype than real threat to this.

Each bulb contains about 5 milligrams ...

And yet, as a high-school chemistry lab assistant, me and my buddy found a quart container full of the stuff. We poured across our hands, held it in our palms and played with it often.

The temp here last night was close to 0, and they were working just fine.

1F when I left for work this morning, porch CFL worked just fine. Sposed to be -8f tomorrow morning. I suspect it's still going to work.

I was at my dads house yesterday and heard a high-pitched noise that gave me a headache. I walked around trying to find the source and it got stronger the closer I got to where he was sitting. I thought maybe it was feedback from his hearing aid or something, but he wasn’t wearing them.

Then I realized it was from the lamp and looked and he said he had just put that new CFL bulb in. I took it out and felt better. Anyone else had headaches from these things or heard very high-pitched noise?

Nothing so far.....but I’m hearing from friends who have them and use then in their garages that on days like today, the car warms up faster than the bulbs do....
